Answer to Question 1

Several factors determine whether food proteins are good sources of essential amino acids to your body. These include whether the protein is complete or incomplete in its pattern of amino acids, and your body's ability to digest and absorb them (i.e., its bioavailability). A protein that provides easily digested and absorbed amino acids has high bioavailability. If a food is a complete protein source and its protein is bioavailable, it is a high-quality protein source. In general, animal-derived foods are sources of high-quality protein, and foods containing incomplete proteins and/or those in which the protein has low bioavailability are low-quality protein sources.
